Principal DevSecOps​/Platform Engineer Security Clearance

Position: Principal DevSecOps / Platform Engineer with Security Clearance
Location: Highland Home

Principal Dev Sec Ops  / Platform Engineer We are seeking a developer-focused Dev Sec Ops  engineer to join a high-performing team building and operating software factories, security automation platforms, and AI-enabled development environments for Department of War and Federal customers. This role emphasizes hands-on software development within a Dev Sec Ops  context - you will write production code, build tooling, and develop applications, not just configure pipelines.

The team supports multiple concurrent internal R&D efforts and customer delivery engagements across defense and federal programs. You will contribute to a range of work streams including agentic AI application development, software factory platform enhancements, security and compliance automation, and secure software delivery for classified environments. MEANINGFUL WORK AND PERSONAL IMPACT
* Work across a broad portfolio rather than a single narrow program - variety and exposure to cutting-edge problems in government software delivery

* Significant investment in AI, automation, and modern platform engineering - not legacy maintenance

* Small, senior team where individual contributions have outsized impact

* Opportunity to shape how the our customers' missions are built and delivered using secure software at scale

* Exposure to Growth activities (proposals, customer engagements) for engineers who want to develop business acumen alongside technical depth

KEY RESPONSIBILITIES Dev Sec Ops  Engineering - Primary Focus Utilize AI-assisted Development tools and frameworks to:
* Design, develop, and maintain CI/CD pipelines for build, test, security scanning, and release across unclassified and classified environments

* Integrate and operate security scanning tool chains (SAST, SCA, container scanning, SBOM generation) as automated pipeline stages

* Use AI-assisted development workflows daily - code generation, automated testing, intelligent code review, and documentation - and champion their adoption across teams

* Contribute to the development of agentic AI capabilities including tool orchestration, prompt engineering, and workflow automation

* Build tooling and automation to support continuous Authority to Operate (cATO) processes, including automated evidence collection, compliance reporting, and policy enforcement

* Develop and maintain hardening pipeline templates that product teams consume for secure-by-default software delivery

* Support platform's security pipeline layer - build, test, and release process for software packages that include both application code and runtime platform components

* Implement and enforce software supply chain security controls (signing, provenance, artifact integrity)

* Troubleshoot build and deployment failures, support development teams consuming shared pipeline services Platform Engineering
* Deploy and operate Kubernetes clusters (Big Bang / Iron Bank baseline) in classified (CUI/IL5) environments

* Deploy, configure, and support AI-powered development tools (Git Lab Duo, LLM-based code assistants, agentic AI frameworks) for platform consumers and internal team use

* Support AI/ML platform infrastructure (model serving, GPU workloads, data pipelines) as part of the broader platform offering

* Stand up and maintain shared platform services:
Harbor (container registry), Nexus (artifact repository), Vault (secrets management), ArgoCD (Git Ops deployment)

* Implement Infrastructure-as-Code for environment provisioning, cluster lifecycle, and configuration management (Terraform, Ansible)

* Support multi-cluster management and hub/spoke deployment models - build in shared services, deploy into downstream accounts

* Configure and troubleshoot network connectivity, Zscaler integration, and Okta/SAML identity federation for platform consumers

* Contribute to platform evolution including self-service name spaces, developer onboarding, and golden-path templates

* Maintain and improve multiple production software factory environments serving diverse federal customers

* Contribute to runbooks, operational documentation, and incident response procedures WHAT YOU'LL NEED TO SUCCEED - REQUIRED SKILLS
